The Eurorack Expansion Project

It’s a never-ending question: “Which module should I get next?” Usually followed by: “If I buy module XYZ module, what new sounds will it make possible? How can I use it to best advantage?” Since few of us live next to a well-stocked modular synth store with an experienced user on hand, I’ve decided to tackle this issue with an ongoing series of videos called the Eurorack Expansion Project. I assume you’re starting with a semi-modular synth (like the Moog Mother-32) or small core modular system, although of course this info will be of use to experienced users as well. These movies go well beyond the simple “here’s what a filter sweep sounds like”, and instead dive into how each module works while teaching a variety of synthesis tricks and techniques along the way.

The Eurorack Expansion Project then continues with additional modules covered on YouTube, with typically 2-4 movies per module. You’ll find many of the videos go beyond the typical knob-twiddling demos, and explain both core and esoteric synthesis techniques. I’ll be covering both new modules and old, including ones I use in my personal system as well as interesting alternatives manufacturers have loaned me to check out. At the beginning of the first video in each set will be a chart showing its size, power demands, and price, including depths I’ve measured myself from the back of a module’s front panel to the back of the power connector or deepest part on the module to make sure it actually fits into your case. These modules will be added to the version of the Eurorack Expansion course offered streaming through this web site.

Additional movies for about half of the modules will be exclusive to the Learning Modular Patreon Tribe: a group of hard-core enthusiasts and eager learners who help support my creation of these movies. Learning Modular patrons also get exclusive access to blog posts based around each movie, and help choose which videos are released next.
